You are currently viewing What are distributed systems, and how do they work?

For distributed systems to function, a task must be divided into smaller subtasks and spread over several nodes or computers in a network. These nodes or computers then communicate and cooperate to finish the task.

The following four steps provide a brief overview of how distributed systems operate:

Decentralized components

A distributed system comprises numerous parts or nodes spread over various real or virtual places. These parts can communicate with one another across a network to accomplish a single objective.


A distributed system’s components can communicate with one another using a variety of protocols and tools, including TCP/IP, HTTP or message queues. These protocols allow the nodes to communicate by sending and receiving messages or data.


For the parts of a distributed system to function well together, they must coordinate their actions. Several mechanisms, such as distributed algorithms, consensus protocols, or distributed transactions, can be used to
